JOSEPH SYLVAN, OF CHICAGO, ILLINOIS, ASSIGNOR 0F ()NE-HALF T0 LOUIS A. BUDA,

. OF CHICAGO, ILLINOIS.

WINDOW.

To all whom it may concern:

Be it known that I, JOSEPH SYLVAN, a subject of the King of Roumania, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Windows; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in automatically opening windows and consists of the matters hereinafter described and more particularly pointed out in the appended claims.

The improved window is of more particular advantage for usein cases where the windows are placed overhead or above the ordinary reach, where difficulty is encountered in opening them. My improved window is also of particular advantage for use in connection with a fusibly supported weight which will act to automatically close the window in case of fire.

In the drawings:

Figure 1 is a view representing, in perspective, two windows arranged side by side, embodying my invention,one of said windows being shown as closed, and the other being shown as open. 7

Fig. 2 is a view representing a vertical section through the window and its frame, in a plane indicated by the line 22 of Fig. l.

Fig. 3 is a similar sectional view, showing the window open.

Fig. 4 is a detail sectional view, on an enlarged scale, in a plane indicated by the line 4.- l of Fig. 2. i

Fig. 5 is a detail, front elevation view,'on an enlarged scale, of the window sill, show ing the actuating chain and its locking clip and a weight member, the purpose of which will appear later.

Fig. 6 is a detail sectional view on an enlarged scale, in a plane indicated by the line 66 of Fig. 2.

Fig. 7 is a perspective view of the top end of the window.

Referring now to that embodiment of my invention illustrated in the drawings :-10 indicates the window casing or frame, and

Application filed. May 17, 1917. Serial No. 169,154.

11 indicates the window. 12 indicates the window sash and 13 the glass window-pane. The window casing or frame 10 and the window sash 12 are preferably made hollow and of sheet metal, although the invention is not limited to the use of metal.

The top member or lintel 10 of the window frame is provided with a horizontal, depending flange or rib 14, against which the outer face of the top frame member or rail 12 of the window sash 12 is adapted to engage when the window is closed. Said rail is provided at its inner face with an upright, horizontal flange 15 which is adapted to engage the inner face of an upright web 16 forming a part of the lintel 10, when the window is closed. This construction of the window frame and sash is reproduced, but reversed at the bottom, the outer face of the bottom member or rail 12 of the window sash being provided with a flange 17 adapted for engagement with the outer face of an upright web 18 forming a part of the sill 19 of the window casing or frame. The inner face of said bottom rail 12 engages against the outer face of a second web20 also forming a part of the window sill 19, said web 20 being spaced inwardly and' arranged in a plane above the other web 18 thereof.

The upright side rails 12 of the window sash are provided with laterally extending flanges 21 On their outer faces, which when the window is closed, engage with the outer faces of upright hollow ribs 22 forming a part of the jambs 23 of the window frame 10. Thus it is apparent that when the window sash 12 is in a closed position with reference to the window frame 10, the flanges 15, 17 and 21 of said window sash together with their associated webs and ribs on the window frame provide an effective seal against the entrance of wind, dust, rain or snow.

Fixed to the ends of the top rails 12 of the window sash, preferably near the flange 15, are laterally projecting pins or trunnions 25 which extend into upright grooves 26 (see Fig. 3) formed in the jambs 23 and provided for by the inner face of the hollow rib 22 and the outer marginal edge of an angular flange 27 also forming a part of said jamb. When the window is in its closed position with reference to the window casing, the marginal, inner edges of the window sash upright rails 12 engage said flanges 27 and close off said groove 26.

The window sash is hinged to swing from the position shown in Fig. 2 to the position shown in Fig. 3. In this movement, the top rail 12 of the sash moves downwardly so as to be disengaged from the lintel, and the bottom rail 12"01 the window sash swings outwardly away from the sill, the trunnions 25 on the window sash sliding downwardly in the grooves 26 in the ambs 23.

Links 28 are pivot-ally connected to the lateral edges of the upright rails 12 of the sash, nearer the top than the bottom end thereof. The other ends of said links are pivotally attached to bent bearing arms 28 provided in the j ambs 23 adjacent the flanges 27. It will be noted from Fig. 2 of the drawings that said links are pivotally connected to the window sash in a vertical plane spaced outwardly from that of the window pane 13 while said links are pivotally connected to the jambs 23 in a vertical plane spaced inwardly from that of the window pane. Thus the weight of the sash as a whole, normally exerts the leverage necessary to the opening swinging movement of the window upon the links 28 before described. As is apparent, it is therefore necessary to lock the window in its closed position and to this end the following means are provided.

Fixed to the inner face of the bottom rail 12 of the window sash at its middle is one end of a chain 29 which is trained about the rolled top end 30 of an angular clip 31 fixed to the inner face of the window sill. The other end of this clip is bent inwardly and has an opening 31 through which the chain 29 extends, the links of said chain being adapted to be caught and held in said opening in a well-known manner. To the free end of said chain, which normally hangs downwardly into a position within reach of the operator, is attached a ring 32 for convenience in grasping the chain when it is desired to open or close the window. Attached to the inner face of the window sill in the vicinity of the clip 31 is a weight member or block 33, said block being cut away to fit about said clip and also having an opening 34L below the hole 31 in said clip and through which the chain 29 extends, said opening 3-1 being smaller in diameter than that of the chain ring 32. This block is preferably attached to the sill 19 by means of wires or cables 35 which terminate in fusible buttons 36 located on that part of the window sill between the upright shoulders or webs 18 and 20.

The operation of the window is as follows. Assuming that the window is in its closed position,v as shown in Fig. 1, and locked in said position by means of the engagement of one of the chain links with the opening 31 in the clip 31. The operator grasps the chain ring 32 and swings the chain inwardly until it can freely pass through the said opening. The window being thus released, will by its own weight and by reason of the connection of the links 28 with the sash and easing, swing outwardly into the position shown in Fig. 3, the trunnions 25 on the top rail moving downwardly in the grooves 26, and the top ends of the lateral flanges 21 sliding on the vertical ribs 22 on the casing. This opening movement will continue until arrested by the binding of the trunnions 25, and of the top ends of the flanges 21 against the vertical ribs 22. It is apparent that the window may be locked in any desired, intermediate, open position between the closed and full open position, by reengagement of the chain with the opening 31 in the clip 31. To close the window it is only necessary to exert a pull on the chain which will produce a reverse of the movement before described.

Assuming that the window is open and a fire is in close proximity thereto and that there is no person at hand to close the window. The heat of the fire will melt the fusible buttons 36 on the window sill which will release their hold upon the wires 35 supporting the weight block 33. The block will then fall from the sill, downwardly about the chain and as the opening insaid block will not permit of the passage of the chain ring through it, said block will, when it engages the said ring 32, provide the necessary pull on the chain to close the window and hold it in closed position.

' My improved window possesses many advantages which are readily apparent. It consists of but few partswhich are easily made and assembled and which cannot get out of order. No springs or other complicated devices are used in opening the window because it opens under its own weight. lVhen in its open position, it presents an opening both above and below the top and bottom edges of said window. The parts are so arranged that but little effort is required to operate the same, and since it antomatically closes in case of fire, it conforms with the requirements of the insurance underwriters.

While in describing my invention I have referred to certain details of mechanical construction and arrangement of parts, I do not wish to be limited thereto, except as may be pointed out in the appended claims.

I claim as my invention:

1. In combination with a window casing having upright jamb grooves, a gravity opening window sash, means normally lockpivoted at one end to said sash near its top end, said links being connected at their other ends to said casing nearer its middle, in a plane spaced to one side of the vertical plane of connection of said links with said sash, said links permitting said sash to swing by gravity into an open position, when the locking means is released, said studs at the top end of the window sash having sliding engagement in said jamb grooves and acting to limit the full opening movement of said window.

2. In combination with a window casing having'jamb members in which are provided upright grooves, a window sash, links pivoted at one end to said casin and at their other ends to said window sas near its top ends, said window sash being capable of a swinging movement on said links under its own weight into an open position, means carried by the top end of the sash and adapted for a sliding engagement in said jamb grooves, and a chain fixed to the bottom end of the sash and adapted to cooperate with a fixed part of the window casing to limit the opening, swinging movement of said window sash.

In testimony that I claim the foregoing as my invention I aflix my signature, in the presence of two witnesses, this 17th day of April, A. D., 1917.
